TECHNICAL FIELD

The present invention relates to methods of identifying candidate compounds for regulating skeletal muscle mass or function or regulating the activity or expression of a corticotropin releasing factor-2 receptor (CRF₂R). The invention also relates to methods for the treatment of skeletal muscle atrophy or methods for inducing skeletal muscle hypertrophy using CRF₂R as the target for intervention and to methods of treating muscular dystrophies using CRF₂R and corticotropin releasing factor-1 receptor (CRF₁R) as targets.

BACKGROUND CRFR and Ligands

There are two corticotropin releasing factor receptors, identified to date (CRF₁R and CRF₂R) which belong to G-protein coupled receptor (GPCR) class. Agonist activation of CRF₁R or CRF₂R leads to G_(αs) activation of adenylate cyclase. Adenylate cyclase catalyzes the formation of cAMP, which in turn has multiple effects including the activation of protein kinase A, intracellular calcium release and activation of mitogen-activated protein kinase (MAP kinase). In other studies, the enhancement of intracellular inositol triphosphate synthesis, after agonist activation of CRF receptors, suggests that CRFRs also couple to G_(αq).

CRF₁R and CRF₂R have been cloned from human, rat, mouse, chicken, cow, catfish, frog and sheep. CRF₁R and CRF₂R each have a unique distribution patterns. In humans three isoforms, alpha, beta and gamma, of the CRF₂R receptor have been cloned. Homologs for alpha and beta CRF₂R have been identified in rat.

Several ligands/agonists of the CRFRs are known. Corticotropin releasing factor (or hormone, CRF or CRH) binds to and activates CRF₁R and CRF₂R. CRF is a major modulator of the body's responses to stress. This 41-amino acid peptide presides over a panoply of neuronal, endocrine, and immune processes as the primary regulator of the hypothalamus-pituitary-adrenal hormonal axis (HPA axis). In addition, there is substantial sequence homology between CRF and the amphibian peptide sauvagine as well as the telostian peptide urotensin, both of which act as agonists of CRF₁R and CRF₂R. These three peptides have similar biological properties as hypotensive agents and ACTH secretogogues. In addition, a mammalian congener of urotensin, urocortin, has been characterized.

The CRF receptors can be distinguished, from non-CRFRs, pharmacologically through the use of receptor selective agonists and antagonists. These selective agonists and antagonist, along with the CRFR knockout mice, have been useful in determining which CRF receptor mediates specific biological responses.

The role of CRF₁R has been fairly well established. Mice in which the CRF₁R gene has been ablated (CRF₁R knockout) demonstrate an impaired stress response and reduced anxiety-like behavior. CRF₁R is a major mediator of the HPA axis. Specifically, corticotropin releasing factor, which is released from the hypothalamus and transported to the anterior pituitary via the hypothalamic-hypophysial portal system, interacts with the CRF₁R present on cells located in the anterior pituitary. Agonist activation of the CRF₁R results in release of ACTH from the cells of the anterior pituitary into the systemic circulation. The released ACTH binds the ACTH receptor present on cells located in the adrenal cortex, resulting in the release of adrenal hormones including corticosteroids. Corticosteroids mediate many effects including, but not limited to, immune system suppression via a mechanism which involves thymic and splenic atrophy. Thus activation of the CRF₁R indirectly results in the down-regulation of the immune system via activation of the HPA axis.

The role of CRF₂R is less well developed. Mice in which the CRF₂R gene has been ablated (CRF₂R knockout) demonstrate an impaired food intake reduction following stimulation with urocortin, lack of vasodilation, but a normal stress response. Experiments with CRF₂R demonstrated that CRF₂R is responsible for the hypotensive/vasodilatory effects of CRFR agonists and for the reduction in food intake observed following treatment of mice with CRFR agonists.

Skeletal Muscle Atrophy and Hypertrophy

Skeletal muscle is a plastic tissue which readily adapts to changes in either physiological demand for work or metabolic need. Hypertrophy refers to an increase in skeletal muscle mass while skeletal muscle atrophy refers to a decrease in skeletal muscle mass. Acute skeletal muscle atrophy is traceable to a variety of causes including, but not limited to: disuse due to surgery, bed rest, or broken bones; denervation/nerve damage due to spinal cord injury, autoimmune disease, or infectious disease; glucocorticoid use for unrelated conditions; sepsis due to infection or other causes; nutrient limitation due to illness or starvation; and space travel. Skeletal muscle atrophy occurs through normal biological processes, however, in certain medical situations this normal biological process results in a debilitating level of muscle atrophy. For example, acute skeletal muscle atrophy presents a significant limitation in the rehabilitation of patients from immobilizations, including, but not limited to, those accompanying an orthopedic procedure. In such cases, the rehabilitation period required to reverse the skeletal muscle atrophy is often far longer than the period of time required to repair the original injury. Such acute disuse atrophy is a particular problem in the elderly, who may already suffer from substantial age-related deficits in muscle function and mass, because such atrophy can lead to permanent disability and premature mortality.

Skeletal muscle atrophy can also result from chronic conditions such as cancer cachexia, chronic inflammation, AIDS cachexia, chronic obstructive pulmonary disease (COPD), congestive heart failure, genetic disorders, e.g., muscular dystrophies, neurodegenerative diseases and sarcopenia (age associated muscle loss). In these chronic conditions, skeletal muscle atrophy can lead to premature loss of mobility, thereby adding to the disease-related morbidity.

Little is known regarding the molecular processes which control atrophy or hypertrophy of skeletal muscle. While the initiating trigger of the skeletal muscle atrophy is different for the various atrophy initiating events, several common biochemical changes occur in the affected skeletal muscle fiber, including a decrease in protein synthesis and an increase in protein degradation and changes in both contractile and metabolic enzyme protein isozymes characteristic of a slow (highly oxidative metabolism/slow contractile protein isoforms) to fast (highly glycolytic metabolism/fast contractile protein isoforms) fiber switch. Additional changes in skeletal muscle which occur include the loss of vasculature and remodeling of the extracellular matrix. Both fast and slow twitch muscle demonstrate atrophy under the appropriate conditions, with the relative muscle loss depending on the specific atrophy stimuli or condition. Importantly, all these changes are coordinately regulated and are switched on or off depending on changes in physiological and metabolic need.

The processes by which atrophy and hypertrophy occur are conserved across mammalian species. Multiple studies have demonstrated that the same basic molecular, cellular, and physiological processes occur during atrophy in both rodents and humans. Thus, rodent models of skeletal muscle atrophy have been successfully utilized to understand and predict human atrophy responses. For example, atrophy induced by a variety of means in both rodents and humans results in similar changes in muscle anatomy, cross-sectional area, function, fiber type switching, contractile protein expression, and histology. In addition, several agents have been demonstrated to regulate skeletal muscle atrophy in both rodents and in humans. These agents include anabolic steroids, growth hormone, insulin-like growth factor I, and beta adrenergic agonists. Together, these data demonstrate that skeletal muscle atrophy results from common mechanisms in both rodents and humans.

While some agents have been shown to regulate skeletal muscle atrophy and are approved for use in humans for this indication, these agents have undesirable side effects such as hypertrophy of cardiac muscle, neoplasia, hirsutism, androgenization of females, increased morbidity and mortality, liver damage, hypoglycemia, musculoskeletal pain, increased tissue turgor, tachycardia, and edema. Currently, there are no highly effective and selective treatments for either acute or chronic skeletal muscle atrophy. Thus, there is a need to identify other therapeutic agents which regulate skeletal muscle atrophy.

Muscular Dystrophies

Muscular dystrophies encompass a group of inherited, progressive muscle disorders, distinguished clinically by the selective distribution of skeletal muscle weakness. The two most common forms of muscle dystrophy are Duchenne and Becker dystrophies, each resulting from the inheritance of a mutation in the dystrophin gene, which is located at the Xp21 locus. Other dystrophies include, but are not limited to, limb-girdle muscular dystrophy which results from mutation of multiple genetic loci including the p94 calpain, adhalin, γ-sarcoglycan, and β-sarcoglycan loci; fascioscapulohumeral (Landouzy-Dejerine) muscular dystrophy, myotonic dystrophy, and Emery-Dreifuss muscular dystrophy. The symptoms of Duchenne muscular dystrophy, which occurs almost exclusively in males, include a waddling gait, toe walking, lordosis, frequent falls and difficulty in standing up and climbing stairs. Symptoms start at about 3-7 years of age with most patients confined to a wheelchair by 10-12 years and many die at about 20 years of age due to respiratory complications. Current treatment for Duchenne muscular dystrophy includes administration of prednisone (a corticosteroid drug), which while not curative, slows the decline of muscle strength and delays disability. Corticosteroids, such as prednisone, are believed to act by blocking the immune cell activation and infiltration which are precipitated by muscle fiber damage resulting from the disease. Unfortunately, corticosteroid treatment also results in skeletal muscle atrophy which negates some of the potential benefit of blocking the immune response in these patients. Thus, there is a need to identify therapeutic agents which slow the muscle fiber damage and delay the onset of disability in patients with muscular dystrophies, but cause a lesser degree of skeletal muscle atrophy than current therapies.

One problem associated with identification of compounds for use in the treatment of skeletal muscle atrophy or of muscular dystrophies has been the lack of good screening methods for the identification of such compounds. Applicants have now found that CRF₂Rs are involved in the regulation of skeletal muscle mass or function and that agonists of CRF₂Rs are able to block skeletal muscle atrophy and/or induce hypertrophy of skeletal muscle. The present invention solves the problem of identifying compounds for the treatment of muscle atrophy by providing screening methods using CRF₂R which can be used to identify candidate compounds useful for the treatment of muscle atrophy. The present invention also solves the problem of finding compounds for treatment of muscle dystrophies by providing a screening method to identify candidate compounds which activate both the CRF₁R and CRF₂R.

SUMMARY OF THE INVENTION

The present invention relates to the use of CRFRs to identify candidate compounds that are potentially useful in the treatment of skeletal muscle atrophy and or to induce skeletal muscle hypertrophy. In particular, the invention provides in vitro methods for identifying candidate compounds for regulating skeletal muscle mass or function comprising contacting a test compound with a cell expressing CRF₂R, or contacting a test compound with isolated CRF₂R, and determining whether the test compound either binds to or activates the CRF₂R.

DETAILED DESCRIPTION OF THE INVENTION I. Terms and Definitions

The following is a list of definitions for terms used herein.

“Agonist” means any compound, including, but not limited to, antibodies, that activates a receptor. For example, CRFR agonists include, but are not limited to, CRF and CRF analogs.

“Allelic variant” means a variant form of a given gene or gene product. One of skill in the art recognizes that a large number of genes are present in two or more allelic forms in a population and some genes have numerous alleles.

“Antibody”, in its various grammatical forms, means immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, i.e., molecules that contain an antigen binding site which specifically binds an antigen. “Purified antibody” means an antibody which has been partially or completely separated from the proteins and naturally-occurring organic molecules with which it is naturally associated. Preferably, the preparation is at least 60% antibody, more preferably at least 75% antibody, more preferably at least 90% antibody, and most preferably at least 99%, by dry weight, antibody.

“Binding affinity” means the propensity for a ligand to interact with a receptor and is inversely related to the dissociation constant for a specific CRF ligand-CRFR interaction. The dissociation constant can be measured directly via standard saturation, competition, or kinetics binding techniques or indirectly via pharmacological techniques involving functional assays and endpoints.

“Chimeric antibody” means an antibody that contains structural elements from two or more different antibody molecules, i.e., from different animal species.

Nos: 4,415,558; 4,489,163; 4,594,329; 4,605,642; 5,109,111; 5,235,036; 5,278,146; 5,439,885; 5,493,006; 5,663,292; 5,824,771; 5,844,074; and 5,869,450. Each of which is incorporated herein by reference. Preferred CRF analogs are sauvagine, urocortin, urocortin-related peptide, urocortin-II and urotensin.

“CRFR agonist” means a compound or molecule which has the ability to activate CRF₁R or CRF₂R, or both. Activation of CRFRs can be measured as described hereinafter.

“CRFR” means CRF₁R or CRF₂R.

“CRF₁R” means any isoforms of CRF₁R from any animal species. The CRF₁R has previously been referred to as CRF-RA, PC-CRF, CRF, (Perrin, M. H., et al. Endocrinology 133:3058-3061 (1993), Chen, R., et al. Proc. Natl. Acad. Sci. USA 90:8967-8971 (1993), Chang, C-P. et al., Neuron 11:1187-1195 (1993), Kishimoto, T., et al., Proc. Natl. Acad. Sci. USA, 92:1108-1112 (1995) and, Vita, N. et al., FEBS Lett. 335: 1-5 (1993)) or the CRH receptor.

The definition of CRF₁R includes, but is not limited to, those receptors for which the cDNA or genomic sequence encoding the receptor has been deposited in a sequence database. These sequences include Accession Nos.: X72304, E11431, L23332, 192584, T37068, T28968, Q81952, L23333, NM_(—)004382, AF180301, T28970, L25438, L24096, 192586, Q81954, AH006791, NM_(—)007762, X72305, AF054582, Y14036, AF229359, AF229361, AB055434 and L41563. The nucleotide and protein sequences of these receptors are available from GenBank or Derwent and for convenience representative sequences are given in the sequence listing herein.

“CRF₂R” means any isoform of CRF₂R from any animal species. CRF₂R has also been referred to as HM-CRF, CRF-RB , (Kishimoto, T., et al., Proc. Natl. Acad. Sci. USA, 92:1108-1112 (1995) and Perrin, M. et al. Proc. Natl. Acad. Sci. USA 92:2969-2973 (1995)).

The definition of CRF₂R receptor includes, but is not limited to, those receptors for which the DNA sequence encoding the receptor has been deposited in a sequence database. These sequences include Accession Nos.: U34587, E12752, NM_(—)001883, T12247, T66508, AF011406, A019381, U16253, T12244, T28972, U17858, NM_(—)009953, Y14037 and AF229360. The nucleotide and protein sequences of these receptors are available from GenBank or Derwent and for convenience, representative sequences are given in the sequence listing herein.

The term “CRFR ” also includes truncated and/or mutated proteins wherein regions of the receptor molecule not required for ligand binding or signaling have been deleted or modified. For example one of skill in the art will recognize that a CRFR with one or more conservative changes in the primary amino acid sequence would be useful in the present invention. It is known in the art that substitution of certain amino acids with different amino acids with similar structure or properties (conservative substitutions) can result in a silent change, i.e., a change that does not significantly alter function. Conservative substitutes are well known in the art. For example, it is known that GPCRs can tolerate substitutions of amino acid residues in the transmembrane alpha-helices, which are oriented toward lipid, with other hydrophobic amino acids, and remain functional. CRF₁Rs differing from a naturally occurring sequence by truncations and/or mutations such as conservative amino acid substitutions are also included in the definition of CRF₁R. CRF₂R differing from a naturally occurring sequence by truncations and/or mutations such as conservative amino acid substitutions are also included in the definition of CRFR₂.

One of skill in the art would also recognize that CRFRs from a species other than those listed above, particularly mammalian species, would be useful in the present invention. One of skill in the art would further recognize that by using probes from the known CRFR species' sequences, cDNA or genomic sequences homologous to the known sequence could be obtained from the same or alternate species by known cloning methods. Such CRF₁R are also included in the definition of CRF₁R and such CRF₂R are also included in the definition of CRF₂R.

In addition, one of skill in the art would recognize that functional allelic variants or functional splice variants of CRFRs might be present in a particular species and that these variants would have utility in the present invention. Splice variants of CRFRs are known, for example U.S. Pat. Nos. 5,888,811; 5,786,203; and 5,728545, each of which is incorporated herein by reference. Such CRF₁R variants are also included in the definition of CRF₁R and such CRF₂R variants are also included in the definition of CRF₂R.

Fusions of a CRF₁R or CRF₂R polypeptide, or a CRF₁R or CRF₂R polypeptide fragment to a non-CRFR polypeptide are referred to as CRFR fusion proteins. Using known methods, one of skill in the art would be able to make fusion proteins of a CRF₁R or a CRF₂R that, while different from native CRF₁R and CRF₂R, would remain useful in the present invention. For example the non-CRFR polypeptide may be a signal (or leader) polypeptide sequence which co-translationally or post-translationally directs transfer of the protein from its site of synthesis to another site (e.g., the yeast α-factor leader). Or the non-CRFR polypeptide may be added to facilitate purification or identification of the CRFR (e.g., poly-His, or Flag peptide). CRF₁R fusion proteins are also included within the definition of CRF₁R and CRF₂R fusion proteins are also included within the definition of CRF₂R.

“CRF₂R signal transduction pathway” means any signaling pathway (e.g., cAMP, MAP kinase) or combination of signaling pathways that are modulated by the binding of endogenous or exogenous ligands to CRF₂R.

“Functional CRFRs” refers to CRFRs, which bind CRF or a CRF analog in vivo or in vitro and are activated as a result of ligand binding.

“Fusion gene” means two or more DNA coding sequences operably associated so as to encode one hybrid protein. A “fusion protein” is the protein product of a fusion gene.

“Inhibit” means to partially or completely block a particular process or activity. For example, a compound inhibits skeletal muscle atrophy if it either completely or partially prevents muscle atrophy.

As used herein, two DNA sequences are said to be “operably associated” if the nature of the linkage between the two DNA sequences does not (1) result in the introduction of a frame-shift mutation, (2) interfere with the ability of a promoter region to direct the transcription of the coding sequences, or (3) interfere with the ability of the corresponding RNA transcript to be translated into a protein. For example, a coding sequence and regulatory sequences are operably associated when they are covalently linked in such a way as to place the transcription of the coding sequence under the influence or control of the regulatory sequences. Thus, a promoter region is operably associated with a coding sequence when the promoter region is capable of effecting transcription of that DNA sequence such that the resulting transcript is capable of being translated into the desired protein or polypeptide.

“Percent identity” means the percentage of nucleotides or amino acids that two sequences have in common, calculated as follows. To calculate the percent identity for a specific sequence (the query), the relevant part of the query sequence is compared to a reference sequence using the BestFit comparison computer program, Wisconsin Package, Version 10.1, available from the Genetics Computer Group, Inc. This program uses the algorithm of Smith and Waterman, Advances in Applied Mathematics, Issue 2: 482-489 (1981). Percent identity is calculated with the following default parameters for the BestFit program: the scoring matrix is blosum62.cmp, the gap creation penalty is 8 and the gap extension penalty is 2. When comparing a sequence to the reference sequence, the relevant part of the query sequence is that which is derived from a CRFR sequence. For example, where the query is a CRFR/purification tag fusion protein, only the CRFR polypeptide portion of the sequence is aligned to calculate the percent identity score.

“Polypeptide” means any chain of amino acids, regardless of length or post-translational modification (e.g., phosphorylation or glycosylation).

“Promoter” means a DNA sequence which controls the initiation of transcription and the rate of transcription from a gene or coding region.

“Prophylactic treatment” means preventive treatment of a subject, not currently exhibiting signs of skeletal muscle atrophy, in order to completely or partially block the occurrence of skeletal muscle atrophy. One of skill in the art would recognize that certain individuals are at risk for skeletal muscle atrophy as discussed in the background section herein. Furthermore, one of skill in the art would recognize that if the biochemical changes leading to skeletal muscle atrophy are appropriately regulated, that the occurrence of atrophy would be prevented or reduced in at-risk individuals. For example, muscular dystrophy patients beginning treatment with corticosteroids are at risk for developing skeletal muscle atrophy indicating that prophylactic treatment of such patients would be appropriate.

“Regulate” in all its grammatical forms, means to increase, decrease or maintain, e.g., to regulate skeletal muscle mass or function means to increase, decrease or maintain the level of skeletal muscle mass or function.

“Regulation of skeletal muscle mass or function” includes regulation of skeletal muscle mass, skeletal muscle function or both.

“Regulatory element” means a DNA sequence that is capable of controlling the level of transcription from an operably associated DNA sequence. Included within this definition of regulatory element are promoters and enhancers. E.g., a CRFR gene regulatory element is a DNA sequence capable of controlling the level of transcription from the CRFR gene.

“Reporter gene” means a coding sequence whose product can be detected, preferably quantitatively, wherein the reporter gene is operably associated with a heterologous promoter or enhancer element which is responsive to a signal which is to be measured. The promoter or enhancer element in this context is referred to herein as a “responsive element”.

“Selective agonist” means that the agonist has significantly greater activity toward a certain receptor(s) compared with other receptors, not that it is completely inactive with regard to other receptors.

“Skeletal muscle hypertrophy” means an increase in skeletal muscle mass or skeletal muscle function or both.

“Skeletal muscle atrophy” means the same as “muscle wasting” and means a decrease in skeletal muscle mass or skeletal muscle function or both.

“Splice variant” means a mRNA or protein which results from alternative exon usage. One of skill in the art recognizes that, depending on cell type, or even within a single cell type, a mRNA may be expressed in a different form, as a splice variant, and thus the translated protein will be different depending upon the mRNA that is expressed.

A “therapeutically effective amount” of a substance is an amount capable of producing a medically desirable result in a treated patient, e.g., decreases skeletal muscle atrophy, increases skeletal muscle mass or increases skeletal muscle function, with an acceptable benefit: risk ratio; in a human or non-human mammal.

“Therapeutic treatment” means treatment of a subject in which an increase in muscle mass or muscle function is desirable. For example, treatment of a subject currently exhibiting signs of skeletal muscle atrophy in order to partially or completely reverse the skeletal muscle atrophy that has occurred or to completely or partially block the occurrence of further skeletal muscle atrophy would be therapeutic treatment of that subject. The term “therapeutic treatment” also includes, for example, treatment of a subject not exhibiting signs of skeletal muscle atrophy to induce skeletal muscle hypertrophy, e.g., treatment of a livestock animal to increase muscle mass.

The term “treatment” means prophylactic or therapeutic treatment.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the arts of protein chemistry, pharmacology, or molecular biology. The methods, materials and examples described herein are not intended to be limiting. Other methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention.

II. The Role of CRFRs in Regulation of Skeletal Muscle Mass

One of skill in the art would recognize the utility of the present invention given the information in the prior art and the teachings below. The results described herein demonstrate that administration of a CRF receptor agonist which activates both CRF₁R and CRF₂R (non-selective CRFR agonist) blocks and/or inhibits the skeletal muscle atrophy inducing effect of denervation, disuse or dexamethasone treatment in models of skeletal muscle atrophy. In addition, data show that CRFR agonists do not show this anti-atrophy effect in mice in which CRF₂R has been knocked out. Also, in rats in which the CRF₁R mediated HPA axis has been interrupted by removal of the adrenal glands (surgical adrenalectomy), treatment of these animals with the non-selective CRFR agonists shows an anti-atrophy effect, indicating that the CRF₂R mediates the anti-atrophy effects. Furthermore, results demonstrate that administration of a non-selective CRFR agonist show a hypertrophy inducing effect. Together, these data demonstrate the modulatory role of the CRF₂R in the process of skeletal muscle atrophy. The specific role of CRFRs in vivo was investigated using the pharmacological agents, sauvagine (Bachem Biosciences, Inc. King of Prussia, PA) and urocortin (Bachem Biosciences, Inc.), which are selective agonists for CRFRs in various models of skeletal muscle atrophy, described hereinafter. These agents have been well characterized and are described in the scientific literature.

FIGS. 1-7 and 9 show the results of experiments demonstrating that administration of selective agonists of CRFRs results in statistically significant inhibition of skeletal muscle atrophy. FIG. 8 shows that the anti-atrophy effect of the CRFR agonist, sauvagine, is mediated through CRF₂R. CRFR agonists administered twice daily in combination with the phosphodiesterase inhibitor, theophylline, resulted in inhibition of skeletal muscle atrophy in animal models of skeletal muscle atrophy. Theophylline was added to potentiate the duration and magnitude of action of the CRFR agonist therefore resulting in increased efficacy of these compounds. Theophylline administered alone in these atrophy models had no effect, demonstrating that the anti-atrophy effect of the CRFR agonist in combination with theophylline was due to the effect of the CRFR agonist. Furthermore, continuous dosing of the CRFR agonist in the absence of theophylline, via osmotic mini-pump, also resulted in inhibition of skeletal muscle atrophy and/or in skeletal muscle hypertrophy. Statistical significance of the results was determined using ANCOVA (Douglas C. Montgomery, Design and Analysis of Experiments, John Wiley and Sons, New York (2^(nd) ed. 1984)). Abbreviations used in FIGS. 1-9: g-gram; SEM-standard error of the mean.

Specifically, FIG. 1 (FIG. 1.) shows that sauvagine inhibits denervation-induced atrophy of the medial gastrocnemius muscle in a mouse sciatic nerve denervation atrophy model.

Legend: A—water only with no dexamethasone included in drinking water (non-atrophied control); B—water+dexamethasone (atrophied control); C—sauvagine (0.1 mg/kg/d)+dexamethasone; D—sauvagine (0.3 mg/kg/d)+dexamethasone; E—sauvagine (1.0 mg/kg/d)+dexamethasone; *−p≦0.05 compared to water; #−p≦0.05 compared to water+dexamethasone. Following the addition of the glucocorticoid, dexamethasone, to the drinking water (1.2 mg/kg/d), male mice were dosed with the above indicated agents or vehicle control (physiological saline) by continuous infusion using an Alzet osmotic minipump at 5 μl/hr until the end of the experimental period (without additional theophylline). The daily delivered dose of sauvagine is as indicated above. Minipump implantation was performed at the time of initiation of dexamethasone exposure. Nine days following the initiation of dosing sauvagine, the medial gastrocnemius and tibialis anterior muscles were removed and weighed to determine the degree of atrophy.

FIG. 4 (FIG. 4.) demonstrates that sauvagine inhibits disuse-induced atrophy of the tibialis anterior (FIG. 4A) and medial gastrocnemius (FIG. 4B) muscles. In addition, statistically significant hypertrophy of the medial gastrocnemius and tibialis anterior muscles of the non-casted leg was also observed with sauvagine treatment. Legend: A—physiological saline (control); B—theophylline; C—sauvagine (0.03 mg/kg)+theophylline; D—sauvagine (0.1 mg/kg)+theophylline; E—sauvagine (0.3 mg/kg)+theophylline; *−p≦0.05 compared to saline. Following casting of the right hind leg, male mice were injected subcutaneously in the midscapular region twice daily, with sauvagine or vehicle control (physiological saline) for ten days at the daily delivered dose indicated. Sauvagine was co-administered with twice daily intraperitoneal dosing of the phosphodiesterase inhibitor theophylline (30 mg/kg). On day ten, the medial gastrocnemius and tibialis anterior muscles were removed and weighed to determine the degree of atrophy.

FIG. 5 (FIG. 5.) demonstrates that both sauvagine and urocortin inhibit denervation-induced atrophy of the tibialis anterior muscle, in a mouse sciatic nerve denervation atrophy model. In addition, hypertrophy of the non-denervated leg was observed with urocortin treatment. Legend: A—water (control); B—sauvagine (1 mg/kg/d); C—urocortin (1.0 mg/kg/d); *−p<0.05 compared to water. Following denervation of the right sciatic nerve, male mice were dosed with the above indicated agents or vehicle control (physiological saline) by continuous infusion using an Alzet osmotic minipump at 5 μl/hr until the end of the experimental period (without additional theophylline). The daily delivered dose of the agents is indicated above. Minipump implantation was performed at the same time as the sciatic nerve denervation. On day nine the tibialis anterior muscle was removed and weighed to determine the degree of atrophy.

FIG. 6 (FIG. 6.) demonstrates that urocortin inhibits disuse-induced atrophy of the tibialis anterior (FIG. 6A) and medial gastrocnemius (FIG. 6B) muscles in the mouse leg casting disuse atrophy model. Legend: A—physiological saline (control); B—urocortin (0.3 mg/kg)+theophylline; *−p<0.05 compared to saline. Following casting of the right hind leg, male mice were injected subcutaneously in the midscapular region twice daily, with urocortin or vehicle control (physiological saline) for ten days. Urocortin was administered at the doses indicated in the description of FIGS. 6A and 6B. Urocortin was co-administered with twice daily intra-peritoneal dosing of the phosphodiesterase inhibitor theophylline (30 mg/kg). On day ten, the medial gastrocnemius and tibialis anterior muscles were removed and weighed to determine the degree of atrophy.

FIG. 7 (FIG. 7) demonstrates that sauvagine inhibits denervation-induced atrophy of the tibialis anterior (FIG. 7A), EDL (FIG. 7B), soleus (FIG. 7C), medial gastrocnemius (FIG. 7D), and plantaris (FIG. 7E) muscles. In addition, sauvagine caused statistically significant hypertrophy of the non-denervated EDL muscle (FIG. 7B). Legend: A—physiological saline (control); B—sauvagine (0.003 mg/kg)+theophylline; C—sauvagine (0.01 mg/kg)+theophylline; D—sauvagine (0.03 mg/kg)+theophylline; #—p<0.05 compared to corresponding controls. Following denervation of the right sciatic nerve, male adrenalectomized rats (adrenalectomized rats were used to remove the skeletal muscle atrophy-inducing effects of activation of the HPA axis via agonisms of the CRF₁R) were injected subcutaneously in the midscapular region twice daily, with either sauvagine or vehicle control (physiological saline) for nine days at the doses shown above. Sauvagine was co-administered with 30 mg/kg theophylline. On day nine, the tibialis anterior, extensor digitorum longus (EDL), soleus, medial gastrocnemius, and plantaris muscles were removed and weighed to determine the degree of atrophy.

FIG. 8 (FIG. 8.) demonstrates that sauvagine inhibits the atrophy observed in wild-type 5 but not CRF₂R knockout mice in the mouse sciatic nerve denervation atrophy model. Legend: A-C—wild-type mice; D-F—CRF₂R knockout mice. A and D—water (control); B and E-—auvagine (0.3 mg/kg/d); C and F—sauvagine (1.0 mg/kg/d); *−p≦0.05 compared to saline. Following denervation of the right sciatic nerve, female wild-type and CRF₂R knockout mice were dosed with sauvagine or vehicle control by continuous infusion using an Alzet osmotic minipump at 5 μl/hr for nine days at the daily delivered dose indicated above. On day nine, the tibialis anterior muscle was removed and weighed to determine the degree of atrophy.

FIG. 9 (FIG. 9) demonstrates that sauvagine inhibits disuse-induced loss of EDL and soleus muscle mass (FIG. 9A) and inhibits loss of muscle function as assessed by measurement of absolute force (FIG. 9B) in the mouse leg casting disuse atrophy model. Legend: A—non casted muscle control; B—casted muscle, saline control; C—casted muscle, sauvagine (0.3 mg/kg)+theophylline (30 mg/kg); *−p≦0.05 compared to saline. Following casting of the right hind leg, male mice were injected subcutaneously in the midscapular region twice daily, with either sauvagine or vehicle control (physiological saline) for ten days at the doses indicated above. Sauvagine was co-administered 30 mg/kg theophylline. On day ten, the EDL and soleus muscles were removed and absolute force and mass measurements taken to determine the degree of atrophy.

III. Preparation of CRFRs, CRF or CRF Analogs, or Cell Lines Expressing CRFRs

CRF₁R, CRF₂R, CRF and CRF analogs can be prepared for a variety of uses, including, but not limited to, the generation of antibodies, use as reagents in the screening assays of the present invention, and use as pharmaceutical reagents for the treatment of skeletal muscle atrophy. It will be clear to one of skill in the art that, for certain embodiments of the invention, purified polypeptides will be most useful, while for other embodiments cell lines expressing the polypeptides will be most useful. For example, in situations where it is important to retain the structural and functional characteristics of the CRFR, e.g., in a screening method to identify candidate compounds which activate CRFRs, it is desirable to use cells which express functional CRFRs.

Because CRF and CRF analogs are short polypeptides, the skilled artisan will recognize that these polypeptides will be most conveniently provided by direct synthesis, rather than by recombinant means, using techniques well known in the art. In addition, many of these molecules are commercially available.

Where the source of CRFRs is a cell line expressing the polypeptide, the cells may, for example, endogenously express CRFR, have been stimulated to increase endogenous CRFR expression or have been genetically engineered to express a CRFR. Methods for determining whether a cell line expresses a polypeptide of interest are known in the art, for example, detection of the polypeptide with an appropriate antibody, use of a DNA probe to detect MRNA encoding the protein (e.g., northern blot or PCR techniques), or measuring binding of an agent selective for the polypeptide of interest (e.g., a radiolabeled selective agonist).

The use of recombinant DNA technology in the preparation of CRF₁R, CRF₂R, or of cell lines expressing these polypeptides is particularly contemplated. Such recombinant methods are well known in the art. To express recombinant CRF₁R or CRF₂R. an expression vector that comprises a nucleic acid which encodes the polypeptide of interest under the control of one or more regulatory elements, is prepared. Genomic or cDNA sequences encoding CRF₁R and CRF₂R from several species have been described and are readily available from the GenBank database or Derwent database as well as in the sequence listing for this application. The accession numbers for CRF₁R and CRF₂R sequences and corresponding SEQ ID NOS. are shown in Table I. Using this publicly available sequence information, one means of isolating a nucleic acid molecule encoding a CRF₁R or CRF₂R is to screen a genomic DNA or cDNA library with a natural or artificially synthesized DNA probe, using methods well known in the art, e.g., by PCR amplification of the sequence from an appropriate library. Another method is to use oligonucleotide primers specific for the receptor of interest to PCR amplify the cDNA directly from mRNA isolated from a particular tissue (such as skeletal muscle). Such isolated mRNA is commercially available. One of skill in the art would also recognize that by using nucleic acid probes corresponding to portions of the known CRFR receptor sequences the homologous cDNAs or genomic sequences from other species can be obtained using known methods. Particularly useful in the methods of the present invention are CRFR receptors from the species including, but not limited to, human, mouse, rat, pig, monkey, chimpanzee, marmoset, dog, cow, sheep, cat, chicken and turkey. By methods well known in the art, the isolated nucleic acid molecule encoding the CRFR of interest is then ligated into a suitable expression vector. The expression vector, thus prepared, is expressed in a host cell and the host cells expressing the receptor are used directly in a screening assay or the receptor is isolated from the host cells expressing the receptor and the isolated receptor is used in a screening assay.

The host-expression vector systems that may be used for purposes of the invention include, but are not limited to: microorganisms such as bacteria (e.g., E. coli, B. subtilis) transformed with recombinant bacteriophage DNA, plasmid DNA, or cosmid DNA expression vectors containing CRFR nucleotide sequences; yeast (e.g., Saccharomyces, Pichia) transformed with recombinant yeast expression vectors containing CRFR nucleotide sequences; insect cell systems infected with recombinant virus expression vectors (e.g., baculovirus) containing CRFR nucleotide sequences; plant cell systems infected with recombinant virus expression vectors (e.g., cauliflower mosaic virus, tobacco mosaic virus) or transformed with recombinant plasmid expression vectors (e.g., Ti plasmid) containing CRFR nucleotide sequences; or mammalian cell systems (e.g., COS, CHO, HEK293, NIH3T3) harboring recombinant expression constructs containing promoters derived from the genome of mammalian cells (e.g., metallothionein promoter) or from mammalian viruses (e.g., retrovirus LTR) and also containing CRFR nucleotide sequences.

The host cell is used to produce the polypeptide of interest. Because the CRFR is a membrane bound molecule, it is purified from the host cell membranes or the CRFR is utilized while anchored in the cell membrane, i.e., whole cells or membrane fractions of cells are used. Purification or enrichment of the CRFRs from such expression systems is accomplished using appropriate detergents and lipid micelles by methods well known to those skilled in the art.

In bacterial systems, a number of expression vectors may be advantageously selected depending upon the use intended for the gene product being expressed. For example, when a large quantity of such protein is produced for the generation of antibodies to CRFRs, vectors which direct the expression of high levels of protein products are desirable. One skilled in the art is able to generate such vector constructs and purify the proteins by a variety of methodologies including selective purification technologies such as fusion protein selective columns and antibody columns, and non-selective purification technologies.

In an insect protein expression system, the baculovirus A. californica nuclear polyhedrosis virus (AcNPV), is used as a vector to express foreign genes in S. frugiperda cells. In this case, CRFR nucleotide sequences are cloned into non-essential regions of the virus and placed under the control of an AcNPV promoter. The recombinant viruses are then used to infect cells in which the inserted gene is expressed and the protein is purified by one of many techniques known to one skilled in the art.

In mammalian host cells, a number of viral-based expression systems may be utilized. Utilization of these expression systems often requires the creation of specific initiation signals in the vectors for efficient translation of the inserted nucleotide sequences. This is particularly important if a portion of the CRFR gene is used which does not contain the endogenous initiation signal. The placement of this initiation signal, in frame with the coding region of the inserted nucleotide sequence, as well as the addition of transcription and translation enhancing elements and the purification of the recombinant protein, are achieved by one of many methodologies known to one skilled in the art. Also important in mammalian host cells is the selection of an appropriate cell type which is capable of the necessary post translational modifications of the recombinant protein. Such modifications, for example, cleavage, phosphorylation, glycosylation, etc., require the selection of the appropriate host cell which contains the modifying enzymes. Such host cells include, but are not limited to, CHO, HEK293, NIH3T3, COS, etc. and are known by those skilled in the art.

For long term, high expression of recombinant proteins, stable expression is preferred. For example, cell lines that stably express CRFRs may be engineered. One of skill in the art, following known methods such as electroporation, calcium phosphate transfection, or liposome-mediated transfection, can generate a cell line that stably expresses CRFRs. This is usually accomplished by transfecting cells using expression vectors which contain appropriate expression control elements (e.g., promoter sequences, enhancer sequences, transcriptional termination sequences, polyadenylation sites, translational start sites, etc.), a selectable marker, and the gene of interest. The selectable marker may either be contained within the same vector, as the gene of interest, or on a separate vector, which is co-transfected with the CRFR sequence containing vector. The selectable marker in the expression vector may confer resistance to the selection and allows cells to stably integrate the vector into their chromosomes and to grow to form foci which in turn can be cloned and expanded into cell lines. Alternatively, the expression vector may allow selection of the cell expressing the selectable marker utilizing a physical attribute of the marker, i.e., expression of Green Fluorescent Protein (GFP) allows for selection of cells expressing the marker using fluorescence activated cell sorting (FACS) analysis.

One of skill in the art is able to select an appropriate cell type for transfection in order to allow for selection of cells into which the gene of interest has been successfully integrated. For example, where the selectable marker is herpes simplex virus thymidine kinase, hypoxanthine-guanine phosphoribosyltransferase or adenine phosphoribosyltransferase, the appropriate cell type would be tk-, hgprt- or aprt-cells, respectively. Or, normal cells can be used where the selectable marker is dhfr, gpt, neo or hygro which confer resistance to methotrexate, mycophenolic acid, G-418 or hygromycin, respectively. Such recombinant cell lines are useful for identification of candidate compounds that affect the CRFR activity.

IV. Preparation of CRFR Antibodies

Antibodies that selectively recognize one or more epitopes of a CRFR are also encompassed by the invention. Such antibodies include, e.g., polyclonal antibodies, monoclonal antibodies, chimeric antibodies, human antibodies, single chain antibodies, Fab fragments, F(ab′)₂ fragments, molecules produced using a Fab expression library, human antibodies (polyclonal or monoclonal) produced in transgenic mice and epitope binding fragments of any of the above. For therapeutic uses, chimeric or human antibodies are preferred; human antibodies are most preferred.

The antibodies can be utilized in conjunction with the compound screening schemes described herein for the evaluation of test compounds, e.g., for immobilization of CRFR polypeptides or such antibodies can be used in conjunction with gene therapy techniques to evaluate, for example, the expression of CRFRs either in cells or directly in patient tissues in which these genes have been introduced. In addition, antibodies of the present invention are useful in the treatment of skeletal muscle atrophy. Antibodies selective for the CRFR can be screened by the methods of the present invention to identify a subset of the antibodies that are CRFR agonists. In addition, anti-idiotype antibodies generated against antibodies specific for CRF or a CRF analog may be useful as CRFR agonists and like anti-CRFR antibodies may be screened for their ability to activate the CRFR by methods of the present invention.

For the production of antibodies, a variety of host animals may be immunized by injection with CRFR, CRF or a CRF analog, anti-CRF antibody, anti-CRF analog antibody, or immunogenic fragments thereof by methods well known in the art. For preparation of an anti-idiotype antibody the immunogen is an anti-CRF antibody or anti-CRF analog antibody. Production of anti-idiotype antibodies is described, for example, in U.S. Pat. No. 4,699,880, incorporated herein by reference. Suitable host animals include, but are not limited to, rabbits, mice, goats, sheep and horses. Immunization techniques are well known in the art. Polyclonal antibodies can be purified from the serum of the immunized animals, or monoclonal antibodies can be generated by methods that are well known in the art. These techniques include, but are not limited to, the well-known hybridoma techniques of Kohler and Milstein, human B-cell hybridoma techniques, and the EBV hybridoma technology. Monoclonal antibodies may be of any immunoglobulin class, including IgG, IgE, IgM, IgA, and IgD containing either kappa or lambda light chains.

Because of the immunogenicity of non-human antibodies in humans, chimeric antibodies are preferred to non-human antibodies when used for therapeutic treatment of human patients. Techniques of producing and using chimeric antibodies are known in the art, and are described in, for example, U.S. Pat. Nos. 5,807,715; 4,816,397; 4,816,567; 5,530,101; 5,585,089; 5,693,761; 5,693,762; 6,180,370; and 5,824,307, all incorporated herein by reference.

Completely human antibodies are particularly desirable for therapeutic treatment of human patients because they are less immunogenic than non-human antibodies or chimeric antibodies. Such antibodies can be produced using transgenic mice which are substantially incapable of expressing endogenous immunoglobulin heavy and light chain genes, but which can express human heavy and light chain genes. The transgenic mice are immunized in the normal fashion with a selected antigen, e.g., all or a portion of CRF₂R. Monoclonal antibodies directed against the antigen are obtained using conventional hybridoma technology from these immunized transgenic mice. This technology is described in detail in U.S. Pat. Nos. 5,874,299; 5,877,397; 5,569,825; 5,661,016; 5,770,429; and 6,075,181, all incorporated herein by reference. As an alternative to obtaining human immunoglobulins directly from the culture of the hybridoma cells, the hybridoma cells can be used as a source of rearranged heavy chain and light chain loci for subsequent expression or genetic manipulation. Isolation of genes from such antibody-producing cells is straightforward since high levels of the appropriate mRNAs are available. The recovered rearranged loci can be manipulated as desired. For example, the constant region can be eliminated or exchanged for that of a different isotype or the variable regions can be linked to encode single chain Fv regions. Such techniques are described in WO 96/33735 and WO 96/34096, all incorporated herein by reference.

V. Selection of Test Compounds

Compounds that can be screened in accordance with the assays of the invention include but are not limited to, libraries of known compounds, including natural products, such as plant or animal extracts, synthetic chemicals, biologically active materials including proteins, peptides such as soluble peptides, including but not limited to members of random peptide libraries and combinatorial chemistry derived molecular library made of D- or L-configuration amino acids, phosphopeptides (including, but not limited to, members of random or partially degenerate, directed phosphopeptide libraries), antibodies (including, but not limited to, polyclonal, monoclonal, chimeric, human, anti-idiotypic or single chain antibodies, and Fab, F(ab′)₂ and Fab expression library fragments, and epitope-binding fragments thereof), organic and inorganic molecules.

In addition to the more traditional sources of test compounds, computer modeling and searching technologies permit the rational selection of test compounds by utilizing structural information from the ligand binding site of CRFR or from already identified agonists of CRFRs. Such rational selection of test compounds can decrease the number of test compounds that must be screened in order to identify a candidate therapeutic compound. CRFRs are GPCRs, and thus knowledge of the CRFR protein sequence allows for the generation of a model of its binding site that can be used to screen for potential ligands. This process can be accomplished in several manners well known in the art. Briefly, the most robust approach involves generating a sequence alignment of the CRFR sequence to a template (derived from the bacterio-rhodopsin or rhodopsin crystal structures or other GPCR model), conversion of the amino acid structures and refining the model by molecular mechanics and visual examination. If a strong sequence alignment cannot be obtained then a model may also be generated by building models of the hydrophobic helices. These are then fitted together by rotating and translating each helix relative to the others starting from the general layout of the known rhodopsin structures. Mutational data that point towards residue-residue contacts may also be used to position the helices relative to each other so that these contacts are achieved. During this process, docking of the known ligands into the binding site cavity within the helices may also be used to help position the helices by developing interactions that would stabilize the binding of the ligand. The model may be completed by refinement using molecular mechanics and loop building of the intracellular and extracellular loops using standard homology modeling techniques. General information regarding GPCR structure and modeling can be found in Schoneberg, T. et. al., Molecular and Cellular Endocrinology, 151:181-193 (1999), Flower, D., Biochimica et Biophysica Acta, 1422:207-234 (1999), and Sexton, P. M., Current Opinion in Drug Discovery and Development, 2(5):440-448 (1999).

Once the model is completed, it can be used in conjunction with one of several existing computer programs to narrow the number of compounds to be screened by the screening methods of the present invention. The most general of these is the DOCK program (UCSF Molecular Design Institute, 533 Parnassus Ave, U64. Box 0446. San Francisco, Calif. 94143-0446). In several of its variants it can screen databases of commercial and/or proprietary compounds for steric fit and rough electrostatic complementarity to the binding site. It has frequently been found that molecules that score well within DOCK have a better chance of being ligands. Another program that can be used is FLEXX (Tripos Inc. 1699 South Hanley Rd. St. Louis, Mo., 63144-2913). This program, being significantly slower, Is usually restricted to searches through smaller databases of compounds. The scoring scheme within FLEXX is more detailed and usually gives a better estimate of binding ability than does DOCK. FLEXX is best used to confirm DOCK suggestions, or to examine libraries of compounds that are generated combinatorially from known ligands or templates.

VI. Screening Assays to Identify Candidate Compounds for the Regulation of Skeletal Muscle Mass or Function

The finding that CRF₂R plays a role in regulating skeletal muscle atrophy enables various methods of screening one or more test compounds to identify candidate compounds that ultimately may be used for prophylactic or therapeutic treatment of skeletal muscle atrophy. This invention provides methods for screening test compounds for their ability to bind to CRF₂R, activate CRF₂R, prolong or augment the agonist-induced activation of CRF₂R or of a CRF₂R signal transduction pathway or increase expression of CRF₂R or CRF genes.

Because CRF₂R and CRF₁R are homologous proteins, it is expected that a certain proportion of agonists for CRF₂R will also function as agonists of CRF₁R. As discussed above, activation of CRF₁R induces activation of the HPA axis and concomitant production of corticosteroids. In most cases in which an increase in muscle mass or function is desired, it is not desirable to activate the HPA axis. Therefore, in addition to screening test compounds for their ability to activate CRF₂R, the invention also provides for the use of CRF₂R and CRF₁R to screen for selective agonists of CRF₂R. When selecting candidate compound useful for the treatment of acute or chronic muscle atrophy, which is not related to muscular dystrophy, it is preferable that the candidate compounds be selective for CRF₂R. Preferably the candidate compound exhibits 10-fold selectivity for CRF₂R versus CRF₁R (i.e., 10-fold more active against CRF₂R than against CRF₁R), more preferably 100-fold selectivity and most preferably 1000-fold or greater selectivity. As published studies have demonstrated a benefit of corticosteroid therapy in the treatment of muscular dystrophies, it may be beneficial that a CRF₂R agonist retain some level of CRF₁R agonism when used to treat muscular dystrophies. Thus, for the treatment of muscular dystrophies, a compound of lower selectivity that activates the CRF₂R as well as the CRF₁R, over a similar concentration range, is preferred. Preferably the candidate compound is 100-fold selective for CRF₂R versus CRF₁R, more preferably 10-fold selective and most preferably not selective for CRF₂R versus CRF₁R (i.e., the activity of the candidate compound is substantially similar for CRF₂R and CRF₁R). Also, in this case, it may be more preferable that the compound is full agonist for CRF₂R while being a partial agonist for CRF₁R. Such a candidate compound would therefore have a built-in limit to the maximum degree of cortisol elevation and potential for muscle atrophy, while the anti-atrophy effect mediated through the CRF₂R could be enhanced by increasing the dose. One of skill in the art would be able to readily determine whether a candidate compound is a full or partial agonist of the CRF₁R or CRF₂R using methods known in the art.

For screening for compounds which ultimately will be used to regulate skeletal muscle mass or function through CRF₂R in humans, it is preferred that the initial in vitro screen be carried out using a CRF₂R with an amino acid sequence that is greater than 80% identical to SEQ ID NO: 10 and more preferably greater than 90% identical to SEQ ID NO: 10. More preferably the test compounds will be screened against a human, mouse or rat CRF₂R, with the most preferable being human. For screening for compounds which ultimately will be used to regulate skeletal muscle mass or function through CRF₂R in a non-human species it is preferable to use the CRF₂R from the species in which treatment is contemplated.

For screening to determine the level of activity that a test or candidate compound has toward CRF₁R to determine what, if any, selectivity a candidate compound exhibits for CRF₂R versus CRF₁R, it is preferred that the initial screen be carried out using a CRF₁R with an amino acid sequence that is greater than 80% identical to SEQ ID NO:2 and more preferably greater than 90% identical to SEQ ID NO:2. More preferably the test compounds will be screened against a human, mouse or rat CRF₁R, with the most preferable being human. For screening for compounds which ultimately will be used to regulate skeletal muscle mass or function in a non-human species, it is preferable to use the CRF₁R from the species in which treatment is contemplated.

The methods of the present invention are amenable to high throughput applications; however, the use of as few as one test compound in the method is encompassed by the term “screening”. Test compounds which bind to CRF₂R, activate CRF₂R, prolong or augment the agonist-induced activation of CRF₂R or of a CRF₂R signal transduction pathway, or increase expression of CRF₂R or CRF genes, as determined by a method of the present invention, are referred to herein as “candidate compounds.” Such candidate compounds can be used to regulate skeletal muscle mass or function. However, more typically, this first level of in vitro screen provides a means by which to select a narrower range of compounds, i.e., the candidate compounds, which merit further investigation in additional levels of screening. The skilled artisan will recognize that a utility of the present invention is to identify, from a group of one or more test compounds, a subset of compounds which merit further investigation. One of skill in the art will also recognize that the assays of the present invention are useful in ranking the probable usefulness of a particular candidate compound relative to other candidate compounds. For instance, a candidate compound which activates CRF₂R at 1000 nM (but not at 10 nM) is of less interest than one which activates CRF₂R at 10 nM. Using such information the skilled artisan may select a subset of the candidate compounds, identified in the first level of screening, for further investigation. By the way of example only, compounds which activate CRF₂R at concentrations of less than 200 nM might be further tested in an animal model of skeletal muscle atrophy, whereas those above that threshold would not be further tested. The skilled artisan will also recognize that, depending on how the group of test compounds is selected, and how the positives are selected, only a certain proportion of test compounds will be identified as candidate compounds, and that this proportion may be very small.

The assay systems described below may be formulated into kits comprising CRF₂R or cells expressing the CRF₂R which can be packaged in a variety of containers, e.g., vials, tubes microtitre well plates, bottles and the like. Other reagents can be included in separate containers and provided with the kit, e.g., positive control samples, negative control samples, buffers and cell culture media.

In one embodiment, the invention provides a method for screening one or more test compounds to identify candidate compounds that bind to CRF₂R. Methods of determining binding of a compound to a receptor are well known in the art. Typically, the assays include the steps of incubating a source of the CRF₂R with a labeled compound, known to bind to the receptor, in the presence or absence of a test compound and determining the amount of bound labeled compound. The source of CRF₂R may either be cells expressing CRF₂R or some form of isolated CRF₂R, as described herein. The labeled compound can be CRF or any CRF analog labeled such that it can be measured, preferably quantitatively (e.g., ¹²⁵I-labeled, europium labeled, fluorescein labeled, GFP labeled, ³⁵S-methionine labeled). Such methods of labeling are well known in the art. Test compounds that bind to the CRFR cause a reduction in the amount of labeled ligand bound to the receptor, thereby reducing the signal level compared to that from control samples (absence of test compound). Variations of this technique have been described in which receptor binding in the presence and absence of G-protein uncoupling agents can discriminate agonists from antagonists (e.g., binding in the absence and presence of a guanine nucleotide analog i.e., GpppNHp). See Keen, M., Radioligand Binding Methods for Membrane Preparations and Intact cells in Receptor Signal Transduction Protocols, R. A. J. Challis, (ed), Humana Press Inc., Totoway N.J. (1997).

Because it is desirable to discriminate between compounds which bind specifically to CRF₂R, as compared with CRF₁R, the assays described above should be conducted using a cell, r membrane from a cell, which expresses only CRF₂R or the assays can be conducted with a ecombinant source of CRF₂R. Cells expressing both forms of CRFR may be modified using homologous recombination to inactivate or otherwise disable the CRF₁R gene. Alternatively, if the source of CRFR contains more than one CRFR type, the background signal produced by the receptor which is not of interest must be subtracted from the signal obtained in the assay. The background response can be determined by a number of methods, including elimination of the signal from the CRFR which is not of interest by use of antisense, antibodies or selective antagonists. Known antagonists of CRFRs include antalarmin (CRF₁R selective), antisauvagine-30 (CRF₂R selective) and astressin (nonselective for CRF₁R/CRF₂R).

In another embodiment, the invention provides methods for screening test compounds to identify candidate compounds which activate CRF₂R and/or CRF₁R. Typically, the assays are cell-based; however, cell-free assays are known which are able to differentiate agonist and antagonist binding as described above. Cell-based assays include the steps of contacting cells which express CRF₁R or CRF₂R with a test compound or control and measuring activation of the CRFR by measuring the expression or activity of components of the CRFR signal transduction pathways.

As described in the background section above, CRFRs appear to couple through several different pathways including G_(αs), G_(αq) or G_(αi), depending upon the cell type. It is thought that agonist activation of CRFR allows the receptor to signal via any of these pathways, provided that the necessary pathway components are present in the particular cell type. Thus, to screen for CRFR activation, an assay can use any of the signal transduction pathways as the readout even if the relevant cell type for treatment, in vivo, couples CRFR to skeletal muscle atrophy via a different pathway. One of ordinary skill in the art would recognize that a screening assay would be effective for identifying useful CRFR agonists independent of the pathway by which receptor activation was measured. Assays for measuring activation of these signaling pathways are known in the art.

For example, after contact with the test compound, lysates of the cells can be prepared and assayed for induction of cAMP. cAMP is induced in response to G_(as) activation. Because G as is activated by receptors other than CRFR and because a test compound may be exerting its effect through CRFRs or by another mechanism, two control comparisons are relevant for determining whether a text compound increases levels of cAMP via activation of a CRFR. One control compares the cAMP level of cells contacted with a test compound and the cAMP level of cells contacted with a control compound (i.e., the vehicle in which the test compound is dissolved). If the test compound increases cAMP levels relative to the control compound this indicates that the test compound is increasing cAMP by some mechanism. The other control compares the cAMP levels of a CRFR expressing cell line and a cell line that is essentially the same except that it does not express the CRFR, where both of the cell lines have been treated with test compound. If the test compound elevates cAMP levels in the CRFR expressing cell line relative to the cell line that does not express CRFRs, this is an indication that the test compound elevates cAMP via activation of the CRFRs.

In a specific embodiment of the invention, cAMP induction is measured with the use of DNA constructs containing the cAMP responsive element linked to any of a variety of reporter genes can be introduced into cells expressing CRFRs. Such reporter genes include, but are not limited to, chloramphenicol acetyltransferase (CAT), luciferase, glucuronide synthetase, growth hormone, fluorescent proteins (e.g., Green Fluorescent Protein), or alkaline phosphatase. Following exposure of the cells to the test compound, the level of reporter gene expression can be quantitated to determine the test compound's ability to increase cAMP levels and thus determine a test compounds ability to activate the CRFR.

The cells useful in this assay are the same as for the CRFR binding assay described above, except that cells utilized in the activation assays preferably express a functional receptor which gives a statistically significant response to CRF or one or more CRF analog. In addition to using cells expressing full length CRFRs, cells can be engineered which express CRFRs containing the ligand binding domain of the receptor coupled to, or physically modified to contain, reporter elements or to interact with signaling proteins. For example, a wild-type CRFR or CRFR fragment can be fused to a G-protein resulting in activation of the fused G-protein upon agonist binding to the CRFR portion of the fusion protein. (Siefert, R. et al., Trends Pharniacol. Sci. 20: 383-389 (1999)). The cells should also preferably possess a number of characteristics, depending on the readout, to maximize the inductive response by CRF or the CRF analog, for example, for detecting a strong induction of a CRE reporter gene; (a) a low natural level of cAMP; (b) G proteins capable of interacting with CRFRs; (c) a high level of adenylyl cyclase; (d) a high level of protein kinase A; (e) a low level of phosphodiesterases; and (f) a high level of cAMP response element binding protein would be advantageous. To increase the response to CRF or a CRF analog, host cells could be engineered to express a greater amount of favorable factors or a lesser amount of unfavorable factors. In addition, alternative pathways for induction of the CRE reporter could be eliminated to reduce basal levels.

In some instances, G protein-coupled receptor responses subside, or become desensitized, after prolonged exposure to an agonist. Another embodiment of the invention provides methods for identifying compounds that prolong or augment the agonist-induced activation of CRF₂R, or the CRF₂R signal transduction pathway, in response to a CRF₂R agonist. Such compounds may be used, for example, in conjunction with a CRF₂R agonist for the treatment of skeletal muscle atrophy. Typically the method uses a cell based assay comprising in any order or concurrently (i) contacting the cells with a test compound; (ii) treating cells expressing functional CRF₂R with a CRF₂R agonist at a concentration of agonist and for a period of agonist-receptor exposure sufficient to allow desensitization of the receptor; followed by (iii) determining the level of activation of the CRF₂R. One of skill in the art will recognize that several mechanisms contribute to receptor desensitization including, but not limited to, receptor phosphorylation, receptor internalization or degradation and CRFR signal transduction pathway down-modulation. One of skill in the art can determine the appropriate time (i.e., before, during or after agonist treatment) for contacting the cells with the test compounds depending upon which mechanism of desensitization is targeted. For example, contacting the cells with test compounds following agonist treatment, can detect test compounds which block receptor desensitization which occurs as a result of phosphorylation of the receptor.

In another embodiment, the invention provides a method of screening one or more test compound to identify candidate compounds which regulate transcription from the CRF₂R gene or regulate CRF₂R expression. Candidate compounds which regulate transcriptional activity of CRFR genes may be identified using a reporter gene operably associated with a CRF₂R regulatory region (reporter gene construct). Such methods are known in the art. In one such method, the reporter gene construct is contacted with a test compound in the presence of a source of cellular factors and the level of reporter gene expression is determined. A test compound which causes an increase in the level of expression, compared to a control sample, is indicative of a candidate compound which increases transcription of the CRF₂R gene. To provide the cellular factors required for in vitro or in vivo transcription, appropriate cells or cell extracts are prepared from any cell type that normally expresses CRF₂R.

Candidate compounds which regulate CRF₂R expression can also be identified in a method wherein a cell is contacted with a test compound and the expression of CRFR is determined. The level of expression of CRF₂R in the presence of the test compound is compared with the level of expression in the absence of the test compound. Test compounds which increase the expression of CRF₂R are identified as candidate compounds for increasing muscle mass or muscle function. Such a method detects candidate compounds which increase the transcription or translation of the CRF₂R or which increase the stability of the MRNA or CRF₂R protein.

In another embodiment, this invention provides methods for screening one or more test compounds to identify candidate compounds which regulate the expression of the CRF or a CRF analog. Such assays are performed essentially as described above for the assays to identify candidate compounds which regulate expression of CRFRs with the following modifications. To identify candidate compound which regulate transcription from the CRF gene or a CRF analog gene, the reporter gene is operably associated with the regulatory region of the CRF gene or CRF analog gene of interest and the source of cellular factors should be from a cell type that expresses the gene of interest.

VII. Screening of Candidate Compounds Using Models of Skeletal Muscle Atrophy

Candidate compounds selected from one or more test compounds by an in vitro assay, as described above, can be further tested for their ability to regulate skeletal muscle mass or function in model systems of skeletal muscle atrophy and/or hypertrophy. Such models of skeletal muscle atrophy or hypertrophy include both in vitro cell culture models and in vivo animal models of skeletal muscle atrophy. Such additional levels of screening are useful to further narrow the range of candidate compounds that merit additional investigation, e.g., clinical trials.

Cell Culture Models of Muscle Atrophy

In vitro models of skeletal muscle atrophy are known in the art. Such models are described, for example, in Vandenburgh, H. H., In Vitro 24:609-619 (1988), Vandenburgh, H. H. et al., J of Biomechanics, 24 Suppl 1:91-99 (1991), Vandenburgh, H.H et al., In Vitro Cell. Dev. Biol., 24(3):166-174 (1988), Chromiak, J. A., et al., In Vitro Cell. Dev. Biol. Anim., 34(9):694-703 (1998), Shansky, J., et al., In Vitro Cell. Dev. Biol. Anim., 33(9):659-661 (1997), Perrone, C. E. et al., J. Biol. Chem. 270(5):2099-2106 (1995), Chromiac, J. A. and Vandenburgh, H. H., J. Cell. Physiol. 159(3):407-414 (1994), and Vandenburgh, H. H. and Karlisch, P., In Vitro Cell. Dev. Biol. 25(7):607-616 (1989). Such models are useful, but not required, following the in vitro screening described above in order to further narrow the range of candidate compounds that merit testing in an animal model. Cell culture models are treated with candidate compounds and the response of the model to the treatment is measured by assessing changes in muscle markers such as: muscle protein synthesis or degradation, changes in skeletal muscle mass or contractile function. Those compounds which induce significant changes in the muscle markers are typically screened further in an animal model of skeletal muscle atrophy.

Animal Models of Skeletal Muscle Atrophy

The candidate compounds are administered to non-human animals and the response of the animals is monitored, for example, by assessing changes in markers of atrophy or hypertrophy such as: skeletal muscle mass, skeletal muscle function, muscle or myofiber cross-sectional area, contractile protein content, non-contractile protein content or a biochemical or genetic marker that correlates with skeletal muscle mass or function changes. Candidate compounds which induce skeletal muscle hypertrophy or prevent any aspect of skeletal muscle atrophy should be considered as prospective therapeutic candidates for treatment of human skeletal muscle atrophy, and are referred to herein as candidate therapeutic compounds. In addition to assessing the ability of a candidate compound to regulate skeletal muscle atrophy, undesirable side effects such as toxicity may also be detected in such a screen. The absence of unacceptably high levels of side effects may be used as a further criterion for the selection of candidate therapeutic compounds.

A variety of animal models for skeletal muscle atrophy are known in the art, such as those described in the following references: Herbison, G. J., et al. Arch. Phys. Med. Rehabil. 60:401-404 (1979), Appell, H-J. Sports Medicine 10:42-58 (1990), Hasselgren, P-O. and Fischer, J. E. World J. Surg. 22:203-208 (1998), Agbenyega, E. T. and Wareham, A. C. Comp. Biochem. Physiol. 102A:141-145 (1992), Thomason, D. B. and Booth, F. W. J. Appl. Physiol. 68:1-12 (1990), Fitts, R. H., et al. J. Appl. Physiol. 60:1946-1953 (1986), Bramanti, P., et al. Int. J. Anat. Embryol. 103:45-64 (1998), Cartee, G. D. J. Gerontol. A Biol. Sci. Med. Sci. 50:137-141 (1995), Cork, L. C., et al. Prog. Clin. Biol. Res. 229:241-269 (1987), Booth, F. W. and Gollnick, P. D. Med. Sci. Sports Exerc. 15:415-420 (1983), Bloomfield, S. A. Med. Sci. Sports Exerc. 29:197-206 (1997). Preferred animals for these models are mice and rats. These models include, for example, models of disuse-induced atrophy such as casting or otherwise immobilizing limbs, hind limb suspension, complete animal immobilization, and reduced gravity situations. Models of nerve damage induced atrophy include, for example, nerve crush, removal of sections of nerves which innervate specific muscles, toxin application to nerves and infection of nerves with viral, bacterial or eukaryotic infectious agents. Models of glucocorticoid-induced atrophy include application of atrophy-inducing doses of exogenous glucocorticoid to animals, and stimulation of endogenous corticosteroid production, for example, by application of hormones that activate the hypothalamus-pituitary-adrenal (HPA) axis. Models of sepsis-induced atrophy include, for example, inoculation with sepsis-inducing organisms such as bacteria, treatment of the animal with immune-activating compounds such as bacterial cell wall extract or endotoxin, and puncture of intestinal walls. Models of cachexia-induced atrophy include, for example, inoculation of an animal with tumorigenic cells with cachexia forming potential, infection of an animal with infectious agents (such as viruses which cause AIDS) which result in cachexia and treatment of an animal with hormones or cytokines such as CNTF, TNF, IL-6, IL-1, etc. which induce cachexia. Models of heart failure-induced atrophy include the manipulation of an animal so that heart failure occurs with concomitant skeletal muscle atrophy. Neurodegenerative disease-induced atrophy models include autoimmune animal models such as those resulting from immunization of an animal with neuronal components. Muscular dystrophy-induced models of atrophy include natural or man-made genetically-induced models of muscular dystrophy such as the mutation of the dystrophin gene which occurs in the Mdx mouse.

Animal models of skeletal muscle hypertrophy include, for example, models of increased limb muscle use due to inactivation of the opposing limb, reweighting following a disuse atrophy inducing event, reutilization of a muscle which atrophied because of transient nerve damage, increased use of selective muscles due to inactivation of a synergistic muscle (e.g., compensatory hypertrophy), increased muscle utilization due to increased load placed on the muscle and hypertrophy resulting from removal of the glucocorticoid after glucocorticoid-induced atrophy. Preferred animal atrophy models include the sciatic nerve denervation atrophy model, glucocorticoid-induced atrophy model, and the leg casting disuse atrophy model that are described in further detail below.

The sciatic nerve denervation atrophy model involves anesthetizing the animal followed by the surgical removal of a short segment of either the right or left sciatic nerve, e.g., in mice the sciatic nerve is isolated approximately at the midpoint along the femur and a 3-5 mm segment is removed. This denervates the lower hind limb musculature resulting in atrophy of these muscles. Typically, innervation to the biceps femoris is left intact to provide satisfactory motion of the knee for virtually normal ambulation. Typically, in untreated animals, muscle mass of the denervated muscles is reduced 30-50% ten days following denervation. Following denervation, test compounds are administered e.g., by injection or by continuous infusion, e.g., via implantation of an osmotic minipump (e.g., Alzet, Palo Alto, Calif.), to determine their effect on denervation induced skeletal muscle atrophy. At various times following denervation, the animals are euthanized and lower leg muscles are dissected rapidly from both the denervated and nondenervated legs, the muscles, cleaned of tendons and connective tissue, are weighed. The extent of atrophy in the affected muscles is analyzed, for example, by measuring muscle mass, muscle cross-sectional area, myofiber cross-sectional area or contractile protein content.

The glucocorticoid-induced atrophy model involves the administration of a glucocorticoid to the test animal, e.g., 1.2 mg/kg/day of dexamethasone in the drinking water. Typically, in untreated animals, skeletal muscle mass is reduced 30-50% following ten days of dexamethasone administration. Concomitantly with, or following glucocorticoid administration, test compounds are administered e.g., by injection or by continuous infusion to determine their effect on glucocorticoid-induced skeletal muscle atrophy. At various times following glucocorticoid administration, the extent of atrophy in the affected muscles is analyzed as described above for the denervation model.

The leg casting disuse atrophy model involves casting one hind leg of an animal from the knee down through the foot. Typically, muscle mass is reduced 20-40% after ten days of casting. Following casting, test compounds are administered by injection or by continuous infusion via implantation of an osmotic minipump (e.g., Alzet, Palo Alto, Calif.) to determine their effect on leg casting induced skeletal muscle atrophy. At various times following leg casting, the extent of atrophy in the affected muscles is analyzed as described above for the denervation model.

One of skill in the art would recognize that in screening for compounds for human use, because there are differences between the human CRF₂R and the CRF₂R from other animal species, there may be some false positive or negative results which arise when the screen is carried out using non-human CRF₂R. Thus, it is preferable to do the initial in vitro screen using human CRF₂R. In certain circumstances, identified candidate compounds may be active toward only the human receptor and not toward a non-human receptor. In such circumstances, it may still be desirable to determine whether these candidate compounds are able to regulate skeletal muscle mass or function in a second level of screening. Because these candidates do not activate non-human CRF₂R, a standard in vivo screen with non-human animal is not advised. In such circumstances the second level of screening for these candidates may be performed in transgenic animals that express human CRFRs.

Animals of any species, especially mammals, including, but not limited to, mice, rats, rabbits, guinea pigs, pigs, goats, dogs and non-human primates may be used to generate CRFR transgenic animals. Mice and rats are preferred, mice are most preferred. A variety of techniques are known in the art and may be used to introduce the human CRFR transgenes into animals to produce the founder lines of transgenic animals. Such techniques include, but are not limited to, pronuclear microinjection, retrovirus-mediated gene transfer into germ lines, gene targeting in embryonic stem cells, electroporation of embryos and sperm-mediated gene transfer.

VIII. Gene Therapy Methods for the Treatment of Skeletal Muscle Atrophy

The overall activity of CRF₂R can be increased by overexpressing a gene for CRF₂R (to increase expression of CRF₂R) or a constitutively active CRF₂R in the appropriate tissue. CRF levels can be increased, in vivo, by likewise overexpressing a CRF gene. Overexpression of these genes will increase the total cellular CRF₂R activity, thus, regulating skeletal muscle atrophy. The gene or genes of interest are inserted into a vector suitable for expression in the subject. These vectors include, but are not limited to, adenovirus, adenovirus associated virus, retrovirus and herpes virus vectors in addition to other particles that introduced DNA into cells (e.g., liposome, gold particles, etc.) or by direct injection of the DNA expression vector, containing the gene of interest, into human tissue (e.g., muscle).

IX. Pharmaceutical Formulations and Methods for Use

Candidate compounds or candidate therapeutic compounds identified by screening methods described herein, can be administered to individuals to treat skeletal muscle atrophy, or to induce skeletal muscle hypertrophy. To this end, the present invention encompasses methods and compositions for modulating skeletal muscle atrophy, including, but not limited to, skeletal muscle atrophy induced by disuse due to surgery, bed rest, broken bones; denervation/nerve damage due to spinal cord injury; autoimmune disease; infectious disease; glucocorticoid use for unrelated conditions; sepsis due to infection or other causes; nutrient limitation due to illness or starvation; cancer cachexia; chronic inflammation; AIDS cachexia; COPD; congestive heart failure; sarcopenia and genetic disorders; e.g., muscular dystrophies, neurodegenerative diseases. Agonists of CRF₂R can be used to inhibit skeletal muscle atrophy. It is not necessary that effective compounds demonstrate absolute specificity for CRFR. It is contemplated that specific antagonist of other affected receptors can be co-administered with an effective, but nonspecific, agonist. Alternately, this lack of specificity may be addressed by modulation of dose alone, or the dosing regimen.

The candidate compounds or candidate therapeutic compounds identified by the screening methods of the present invention may be administered in conjunction with compounds which prolong or augment the activation of a CRF₂R or of a CRF₂R signal transduction pathway. These may be known compounds, for example, theophylline, or these compounds may be identified by the screening methods of this invention to prolong or augment the activation of a CRF₂R receptor or of a CRF₂R signal transduction pathway.

Dose Determinations

Safety and therapeutic efficacy of compounds which agonize CRFR can be determined by standard procedures using either in vitro or in vivo technologies. Compounds which exhibit large therapeutic indices are preferred, although compounds with lower therapeutic indices are useful if the level of side effects is acceptable. The data obtained from the in vitro and in vivo toxicological and pharmacological techniques can be used to formulate the human range of doses which may be useful. The preferred dose lies in the range in which the circulating concentration of the compound is therapeutically maximal with acceptable safety. The circulating concentration of the compound may vary depending on the dose form, time after dosing, route of administration, etc. Doses outside this range are also useful provided the side effects are acceptable. Such matters as age and weight of the patient, and the like, can be used to determine such matters in the conventional manner. Pharmacogenetic approaches may be useful in optimizing compound selection, doses and dosing regimen in clinical populations.

Formulation and Use

Pharmaceutical compositions for use in the modulation of skeletal muscle atrophy in accordance with the present invention may be formulated using conventional methodologies using pharmaceutically acceptable carriers and excipients. The compositions of this invention are preferably provided in unit dosage form. As used herein, a “unit dosage form” is a composition of this invention containing an amount of a CRF₂R agonist that is suitable for administration to an animal, preferably a mammal, more preferably a human subject, in a single dose, according to good medical practice. Pharmaceutical compositions may be formulated for delivery by, for example, intranasal, transdermal, inhalation, parenteral, cutaneous, oral or rectal administration. For oral administration, the pharmaceutical composition may take the form of tablets or capsules containing the pharmacologically active compound and additives including, but not limited to, binding agents, fillers, lubricants, disintegrants, or wetting agents. The tablets may be coated. Liquid preparations for oral administration include, but are not limited to, syrups, suspensions or dry products which are reconstituted with liquid vehicle before use, containing the pharmacologically active compound and additives including, but not limited to, suspending agents, emulsifying agents, non-aqueous vehicles, preservatives, buffer salts, flavoring , coloring, sweetening agents, etc. Pharmaceutical compositions for oral administration may be formulated for controlled release of the pharmacologically active compounds either in the mouth, stomach or intestinal tract.

For inhalation administration, the compounds for use according to the present invention may be delivered by, but not limited to, the following forms: liquid, powder, gel or in the form of an aerosol spray utilizing either pressurized or non-pressurized propellants in either premeasured or non-premeasured doses. The pharmacologically active compound may be formulated with appropriate fillers, vehicles, preservatives, buffers, etc. For parenteral administration, the pharmacologically active compound may be formulated with acceptable physiological carriers, preservatives, etc. and be prepared as suspensions, solutions, emulsion, powders ready for constitution, etc. for either bolus injection or infusion. Doses of these compounds may be administered by a variety of technologies including hypodermic needles, high pressure devices, etc. For rectal administration, the pharmacologically active compound may be formulated with acceptable physiological carriers, preservatives, etc. for delivery as suppositories, enemas, etc. For cutaneous administration, the pharmacologically active compound may be formulated with acceptable physiological carriers including lotions, emollients, etc. or incorporated into a patch type device. For long term administration, the pharmacologically active compound and appropriate additives such as, but limited to, polymers, hydrophobic materials, resins, etc. may be formulated as a depot preparation for either injection or implantation at multiple sites including but not limited to intramuscular and subcutaneous locations. In addition, the pharmacologically active compound may be administered by a dispensing device.

Monitoring of Effects During Clinical Trials

Monitoring the influence of compounds (e.g., drugs) on the expression or activity of CRF₂R can be employed not only in basic drug screening, but also in clinical trials. For example, the effectiveness of a compound determined by a screening assay to increase CRF₂R receptor activity or CRF₂R receptor expression can be assessed in clinical trials of patients with, or at risk for, skeletal muscle atrophy. At various times following administration of the test compound or placebo, the effect of the compound on the patient can be determined, for example, by observing the change in skeletal muscle mass, skeletal muscle function, biochemical markers of muscle breakdown or quality of life measures. Methods of measuring skeletal muscle mass in human subjects are known in the art and include, for example: measuring the girth of a limb; measuring muscle thickness with for instance, computer tomography, MRI or supersonics; or muscle biopsy to examine morphological and biochemical parameters (e.g., cross-section fiber area, fiber diameter or enzyme activities). Furthermore, because skeletal muscle mass is correlated with skeletal muscle function, muscle function can be used as a surrogate marker of mass and muscle mass changes can be assessed using functional measurements, e.g., strength, the force of a group of synergist muscles, or contraction characteristics found in electromyographic recordings. In addition, muscle protein loss as a result of muscle atrophy can be measured by quantitating levels of amino acids or amino acids derivatives, i.e., 3-methyl histidine, in the urine or blood of a subject. For a review of such methods see Appell, Sports Med. 10:42-58 (1990). Quality of life measures include, but are not limited to, the ease of getting out of a chair, number of steps taken before tiring or ability to climb stairs.

EXAMPLES Example 1 Construction of Vectors for Human CRF₂R Receptor Expression.

The human CRF₂R (hCRF₂R) DNA sequence, Accession No. E12752, is retrieved and two oligonucleotides including one containing the 5′ end of the gene beginning at the initiation codon (5′ oligonucleotide) and one containing the 3′ end of the gene containing the stop codon (3′ oligonucleotide) are synthesized. These oligonucleotides are designed to contain restriction endonuclease sites which are not present in the hCRF₂R gene with one unique site in the 5′ oligonucleotide and a different unique restriction endonuclease site in the 3′ oligonucleotide In addition, the 3′ oligonucleotide contains a polyadenylation addition signal sequence. Double stranded cDNA from human skeletal muscle is purchased from the Universal QUICK-Clone cDNA collection (Clonetech Inc., Palo Alto, Calif., USA). Using the above 5′ and 3′ oligonucleotides, the hCRF₂R cDNA is amplified by PCR of the human skeletal muscle cDNA using the AdvanTaq PCR kit (Clonetech Inc., Palo Alto, Calif., USA). The hCRF₂R gene PCR product is purified from PCR artifacts by agarose gel electrophoresis and the hCRF₂R gene DNA fragment is purified from the agarose gel using a purification product such as NucleoTrap (Clonetech Inc., Palo Alto, Calif., USA).

Cloning of the hCRF₂R PCR product into the pIRESneo vector (Clonetech Inc., Palo Alto, Calif., USA) is accomplished by first cutting the hCRF₂R PCR product and the pIRESneo vector with the appropriate restriction endonucleases so that the 5′ and 3′ restriction endonuclease sites are ready for ligation. The pIRESneo vector DNA is ligated to the hCRF₂R PCR product DNA using DNA ligase, from the AdvantAge TPCR Cloning Kit (Clonetech Inc., Palo Alto, Calif., USA), according to the manufacturer's recommendations. The ligated vector and insert construct (pIRESneo/hCRF₂R)is then used to transform TOP10F′ competent E. coli cells (Clonetech Inc., Palo Alto, Calif., USA). Transformed cells are plated on LB/X-gal/IPTG plus ampicillin containing agar. White colonies (positive clones) are selected and individually cultured in LB medium. Plasmid DNA is isolated using NucleoBond DNA Purification System (Clonetech Inc., Palo Alto, Calif., USA). The insert from at least one clone is sequenced to ensure that the hCRF₂R sequence is correct. HEK293 cells containing a stably integrated Mercury CRE-LUC plasmid (Clonetech Inc., Palo Alto, Calif., USA) are transfected with purified pIRESneo/hCRF₂R DNA, having the correct sequence insert, utilizing the CalPhos™ Mammalian Transfection Kit (Clonetech Inc., Palo Alto, Calif., USA. Cells stably transfected with pIRESneo/hCRF₂R DNA are selected by culturing the cells in G418. The stably transfected cells (HEK293/CRE-LUC/pIRESneo/hCRF₂R cells) are propagated in DMEM (Life Technologies, Rockville, Md.) containing 10% fetal bovine serum (Clonetech Inc., Palo Alto, Calif., USA), penicillin/streptomycin solution (Life Technologies, Rockville, Md.), L-glutamine (Life Technologies, Rockville, Md.), and non-essential amino acid (Life Technologies, Rockville, Md.) at 37° C. in a 5% carbon dioxide/95% air atmosphere. The clones are characterized for both CRF binding and CRE-LUC activation following exposure to CRF as described in Example 2 and Example 3. Cells expressing the hCRF₂R receptor at an appropriate level and which are appropriately coupled to the CRE-LUC reporter system are then utilized for further analysis.

Example 2 Receptor Binding Assays

Receptor binding analysis of compounds is performed in whole cells by plating the HEK293/CRE-LUC/pIRESneo/hCRF₂R cells from Example 1 in a 96 well polylysine coated plate. Cells are seeded in DMEM medium containing 10% fetal bovine serum, penicillin/streptomycin solution, L-glutamine, and non-essential amino acid at 37° C. in a 5% carbon dioxide/95% air atmosphere and incubated overnight. The culture medium is removed and the appropriate amount of CRF covalently labeled with Europium (Eu-CRF) in MEM (Life Technologies, Rockville, Md.)+10% Seablock (Clonetech Inc., Palo Alto, Calif., USA) is added. The cells are incubated with the Eu-CRF for 90 minutes at room temperature then washed 4 times with phosphate buffered saline lacking magnesium and calcium (Life Technologies, Rockville, Md.). Following the final wash, enhancement solution is added (Wallac Inc., Gaithersburg, Md.) and the plate is read on a Wallac plate reader (Wallac Inc., Gaithersburg, Md.) using the BioWorks Europium program. For saturation binding analysis, log doses of Eu-CRF ranging from 10(−12) to 10(−3) M are added to the cells and binding analyzed both in the absence and the presence of a saturating concentration of unlabeled CRF for evaluation of non-specific binding. For competitive binding, a concentration of Eu-CRF is added which is half maximal, in terms of binding, in addition to varying concentrations of the compound of interest.

Example 3 Receptor Activation Assay

Receptor activation analysis is performed by seeding the HEK293/CRE-LUC/pIRESneo/hCRF₂R cells of Example 1 into Packard View Plate-96 (Packard Inc., Calif.). Cells are seeded in DMEM medium containing 10% fetal bovine serum, penicillin/streptomycin solution, L-glutamine, and non-essential amino acid at 37° C. in a 5% carbon dioxide/95% air atmosphere and incubated overnight. The medium is then removed and replaced with DMEM (Life Technologies, Rockville, Md.) containing 0.01% bovine albumin fraction V (SIGMA, St. Louis, Mo.) containing the compound of interest. The cells are then incubated for four hours at 37° C. in a 5% carbon dioxide/95% air atmosphere after which the medium is removed and the cells are washed twice with Hanks Balanced Salt Solution (Life Technologies, Rockville, Md.). Lysis Reagent (Promega Inc., Madison, Wis.) is then added to the washed cells and the cells are incubated for 20 minutes at 37° C. in a 5% carbon dioxide/95% air atmosphere. The cells are then placed at −80° C. for 20 minutes followed by a 20 minute incubation at 37° C. in a 5% carbon dioxide/95% air atmosphere. After this incubation, Luciferase Assay Buffer and Luciferase Assay Substrate (Promega Inc., Madison, Wis.) are added to the cell lysates and luciferase activity quantitated using a luminometer. Relative activity of a compound is evaluated by comparing the increase following exposure to compound to the level of luciferase in HEK cells which contain the CRE-LUC construct without the hCRP₂R following exposure to compound. Specificity of response is also checked by evaluating luciferase response of hCRF₂R/CRE-LUC HEK cells to compound in the presence and absence of a 10-fold excess of hCRF₂R antagonist.

Example 4 Screen to Identify Candidate Compounds that Prolong or Augment the Activation of CRF₂R and/or a CRF₂R Receptor Signal Transduction Pathway

Identification of compounds that prolong or augment the agonist-induced activation of the CRF₂R or of a CRF₂R signal transduction pathway, involves a variation of the Receptor Activation Assay described in Example 3. Specifically, this assay is performed by seeding the HEK293/CRE-LUC/pIRESneo/hCRF₂R receptor cells into Packard View Plate-96 (Packard Inc., Calif.). Cells are seeded in DMEM medium containing 10% fetal bovine serum, penicillin/streptomycin solution, L-glutamine, non-essential amino acid, and saturating amounts of CRF at 37° C. in a 5% carbon dioxide/95% air atmosphere and incubated for 48 hours. The medium is then removed and replaced with DMEM (Life Technologies, Rockville, Md.) containing 0.01% bovine albumin fraction V (SIGMA, St. Louis, Mo.) and CRF in addition to the compound of interest. The cells are then incubated for four hours at 37° C. in a 5% carbon dioxide/95% air atmosphere after which the medium is removed and the cells are washed twice with Hanks Balanced Salt Solution (Life Technologies, Rockville, Md.). Lysis Reagent (Promega Inc., Madison, Wis.) is then added to the washed cells and the cells are incubated for 20 minutes at 37° C. in a 5% carbon dioxide/95% air atmosphere. The cells are then placed at −80° C. for 20 minutes followed by a 20 minute incubation at 37° C. in a 5% carbon dioxide/95% air atmosphere. After this incubation, Luciferase Assay Buffer and Luciferase Assay Substrate (Promega Inc., Madison, Wis.) are added to the cell lysates and luciferase activity is quantitated using a luminometer. Test compounds which stimulate fluorescence significantly above the levels of control untreated cells, after correction for variations in cell density, are considered candidate compounds for regulating skeletal muscle mass or function. The compounds of most interest are those that induce relatively higher levels of fluorescence.

Example 5 Screen to Identify Candidate Compounds Specific for CRF₂R.

Compounds that activate CRF₂R are identified as in Example 3. To select those compounds which show selectivity for CRF₂R over CRF₁R, these compounds also are screened against CRF₁R. HEK293/CRE-LUC/pIRESneo/hCRF₁R cells are generated essentially as described in Example 1 except that the human CRF₁R (hCRF₁R) DNA sequence, Accession No. X72304, is used for the initial PCR amplification. To determine how active the compounds are against CRF₁R, an activation assay is performed essentially as described in Example 3 except that HEK293/CRE-LUC/pIRESneo/hCRF₁R cells are used to seed the plates. The amount of fluorescence stimulated by the compound in CRF₂R expressing cells is compared with the amount of fluorescence stimulated by the compound in CRF₁R expressing cells. Those compounds which demonstrate a 10-fold better response (on a molar basis) in CRF₂R expressing cells than in CRF₁R expressing cells are then checked further for specificity of response to eliminate differences due to clonal variation. HEK293/CRE-LUC/pIRESneo/hCRF₂R cells are assayed with the compound in the presence or absence of a 10-fold excess of the CRF₂R antagonist, antisauvagine-30. Those compounds that show greater than 10-fold selectivity for CRF₂R and whose activity is inhibited by antisauvagine-30 are selected as candidate compounds.

Example 6 Screens to Identify Candidate Compounds that Increase hCRF₂R Expression

The sequence containing the promoter region of the hCRF₂R gene, beginning far enough upstream of the transcriptional initiation site to contain all the regulatory elements necessary for physiological expression of the hCRF₂R gene in the appropriate tissue is retrieved from the human genome database. Two oligonucleotides, one containing the 5′ end of the promoter region (5′ oligonucleotide) and one containing the 3′ end of the promoter region including the transcriptional start site (3′ oligonucleotide) are synthesized. These oligonucleotides also contain restriction endonuclease sites which are not present in the hCRF₂R gene regulatory region with one unique site in the 5′ oligonucleotide and a different unique restriction endonuclease site in the 3′ oligonucleotide. The 5′ and 3′ oligonucleotides are used for PCR amplification of the hCRF₂R gene regulatory region from human DNA (Clonetech Inc., Palo Alto, Calif., USA) using the PCR kit, Advantage®Genomic PCR kit (Clonetech Inc., Palo Alto, Calif., USA). The hCRF₂R gene regulatory region PCR product is purified from PCR artifacts by agarose gel electrophoresis and the hCRF₂R gene regulatory region DNA fragment is purified from the agarose gel using a purification product such as NucleoTrap (Clonetech Inc., Palo Alto, Calif., USA). Cloning of the hCRF₂R gene regulatory region PCR product into the pECFP-1 vector (Clonetech Inc., Palo Alto, Calif., USA) is accomplished by first cutting the hCRF₂R gene regulatory region PCR product and the pECFP-1 vector with the appropriate restriction endonucleases so that the 5′ and 3′ restriction endonuclease sites are ready for ligation. Ligation of the pECFP-1 vector DNA to the hCRF₂R gene regulatory region PCR product DNA is accomplished using DNA ligase from the AdvantAge™PCR Cloning Kit (Clonetech Inc., Palo Alto, Calif., USA) according to the manufacturer's recommendations. The ligated vector and insert construct is then used to transform TOP10F′ competent E. coli cells (Clonetech Inc., Palo Alto, Calif., USA). The cells are plated on LB plus kanamycin containing agar and kanamycin resistant colonies are selected for further analysis. Kanamycin resistant clones are cultured in LB containing kanamycin medium and plasmid DNA is isolated using NucleoBond DNA Purification System (Clonetech Inc., Palo Alto, Calif., USA) and the construct containing the hVPAC₂ gene regulatory region is analyzed by DNA sequencing to ensure construct correctness and integrity. Purified construct plasmid DNA containing the hCRF₂R gene regulatory region is then transfected into the HEK293 cells utilizing calcium phosphate-mediated transfection utilizing the CalPhosT Mammalian Transfection Kit (Clonetech Inc., Palo Alto, Calif., USA). Transfected cell clones are selected using G418, isolated and propagated in DMEM (Life Technologies, Rockville, Md.) containing 10% fetal bovine serum (Clonetech Inc., Palo Alto, Calif., USA), penicillin/streptomycin solution (Life Technologies, Rockville, Md.), L-glutamine (Life Technologies, Rockville, Md.), non-essential amino acid (Life Technologies, Rockville, Md.) and G418 (Life Technologies, Rockville, Md.) at 37° C. in a 5% carbon dioxide/95% air atmosphere. G418 resistant clones are characterized by Southern blotting to ensure that they contain the hCRF₂R gene promoter sequence; in addition activation of the hCRF₂R gene regulatory region is analyzed using an appropriate stimulating agent. Cells expressing the hCRF₂R gene regulatory region-ECFP at an appropriate level are then used in assays designed to evaluate compounds which can modulate the activity of the hCRF₂R gene regulatory region as follows. The regulatory region activation analysis is performed by seeding the hCRF₂R gene regulatory region-ECFP containing HEK293 cells at an appropriate density into black with clear bottom 96 well microtiter plates and allowed to grow overnight. The following day, the medium is removed and the test compound added in fresh growth medium. The cells are incubated for 16 hours at 37° C. in a 5% carbon dioxide/95% air atmosphere followed by measurement of fluorescence (excitation at 433 (453) nm by detecting emission at 475(501) nm using a fluorometer (biolumin™ 960, Molecular Dynamics/Amersham Pharmacia Biotech, Piscataway, N.J.). Test compounds which stimulate fluorescence significantly above the levels of control untreated cells, after correction for variations in cell density, are considered candidate compounds for regulating skeletal muscle mass or function. The compounds of most interest are those which induce relatively higher levels of fluorescence.

Example 7 Screens to Identify Compounds that Increase Human CRF Expression

The methods for identifying compounds that increase human CRF (hCRF) expression are essentially identical to those for identifying compounds which increase hVPAC₂ receptor expression except the regulatory region used is that for the hCRF gene. The sequence containing the regulatory region of the hCRF gene, beginning far enough upstream of the transcriptional initiation site to contain all the regulatory elements necessary for physiological expression of the hCRF gene in the appropriate tissue is retrieved from the human genome database. Two oligonucleotides, one containing the 5′ end of the regulatory region (5′ oligonucleotide) and one containing the 3′ end of the regulatory region including the transcriptional start site (3′ oligonucleotide) are synthesized. These oligonucleotides also contain restriction endonuclease sites which are not present in the hCRF gene regulatory region with one unique site in the 5′ oligonucleotide and a different unique restriction endonuclease site in the 3′ oligonucleotide. The 5′ and 3′ oligonucleotides are used for PCR amplification of the hCRF gene regulatory region from human DNA (Clonetech Inc., Palo Alto, Calif., USA) using the Advantage®Genomic PCR kit (Clonetech Inc., Palo Alto, Calif., USA). The hCRF gene regulatory region PCR product is purified from PCR artifacts by agarose gel electrophoresis and the hCRF gene regulatory region DNA fragment is purified from the agarose gel using the purification product, NucleoTrap (Clonetech Inc., Palo Alto, Calif., USA). Cloning of the hCRF gene regulatory region PCR product into the pECFP-1 vector (Clonetech Inc., Palo Alto, Calif., USA) is accomplished by first cutting the hCRF gene regulatory region PCR product and the pECFP-1 vector with the appropriate restriction endonucleases so that the 5′ and 3′ restriction endonuclease sites are ready for ligation. Ligation of the pECFP-1 vector DNA to the hCRF gene regulatory region PCR product DNA is accomplished using DNA ligase from AdvantAge TPCR Cloning Kit (Clonetech Inc., Palo Alto, Calif., USA) according to the manufacturer's recommendations. The ligated vector and insert construct is then used to transform TOP10F′ competent E. coli cells (Clonetech Inc., Palo Alto, Calif., USA). The cells are plated on LB plus kanamycin containing agar and kanamycin resistant colonies are selected for further analysis. Kanamycin resistant clones are cultured in LB containing kanamycin medium and plasmid DNA is isolated using NucleoBond DNA Purification System (Clonetech Inc., Palo Alto, Calif., USA) and the construct containing the hCRF gene regulatory region is analyzed by DNA sequencing to ensure construct correctness and integrity. Purified construct plasmid DNA containing the hCRF gene regulatory region is then transfected into the HEK293 cells utilizing calcium phosphate-mediated transfection utilizing the CalPhos™ Mammalian Transfection Kit (Clonetech Inc., Palo Alto, Calif., USA). Transfected cell clones are selected using G418, isolated and propagated in DMEM (Life Technologies, Rockville, Md.) containing 10% fetal bovine serum (Clonetech Inc., Palo Alto, Calif., USA), penicillin/streptomycin solution (Life Technologies, Rockville, Md.), L-glutamine (Life Technologies, Rockville, Md.), non-essential amino acid (Life Technologies, Rockville, Md.) and G418 (Life Technologies, Rockville, Md.) at 37° C. in a 5% carbon dioxide/95% air atmosphere. G418 resistant clones are characterized by Southern blotting to ensure that they contain the hCRF gene regulatory region sequence; in addition activation of the hCRF gene regulatory region is analyzed using an appropriate stimulating agent. Cells expressing the hCRF gene regulatory region-ECFP at an appropriate level are then used in assays designed to evaluate compounds which can modulate the activity of the hCRF gene regulatory region as follows. The regulatory region activation analysis is performed as in Example 5 except that clones containing the hCRF gene regulatory region construct are used.

Example 8 Method of Making Human Antibodies which Activate the hCRF₂R

Fully human monoclonal antibodies which activate the hCRF₂R are produced by first generating recombinant hCRF₂R protein as follows. The procedure from Example 1 is followed to obtain the hCRF₂R PCR product. This hCRF₂R PCR product is then cloned into the pHAT20 vector (Clonetech Inc., Palo Alto, Calif., USA) by first cutting the hCRF₂R gene PCR product and the pHAT20 vector with the appropriate restriction endonucleases so that the 5′ and 3′ restriction endonuclease sites are ready for ligation. Ligation of the pHAT20 vector DNA to the hCRF₂R gene PCR product DNA is accomplished using DNA ligase from the AdvantAge™PCR Cloning Kit (Clonetech Inc., Palo Alto, Calif., USA) according to the manufacturer's recommendations. The ligated vector/insert construct is then used to transform TOP10F′ competent E. coli cells (Clonetech Inc., Palo Alto, Calif., USA). Transformed cells are plated on LB plus ampicillin containing agar and ampicillin resistant colonies are selected for further analysis. Positive clones are cultured in LB medium containing ampicillin and plasmid DNA is isolated using NucleoBond DNA Purification System (Clonetech Inc., Palo Alto, Calif., USA) and the construct containing the hCRF₂R gene is analyzed by DNA sequencing the ensure construct correctness and integrity. The hCRF₂R-pHAT20 vector DNA is then used for additional PCR cloning by utilizing a 5′oligonucleotide containing the beginning of the HAT sequence and a unique restriction endonuclease site not present in the hCRF₂R-pHAT20 construct and the 3′ hCRF₂R oligonucleotide utilized previously. The oligonucleotide primers are used to PCR amplify the HAT-hCRF₂R fusion gene from the hCRF₂R-pHAT20 construct and the PCR product is purified as described above. The HAT-hCRF₂R fusion gene PCR product is then utilized for cloning into the pBacPAK8 vector using the BacPAK Baculovirus Expression System from Clonetech (Clonetech Inc., Palo Alto, Calif., USA). The ligation of the HAT-hCRF₂R fusion gene into the pBacPAK8 vector is essentially as described above. The hCRF₂R/HAT-pBacPAK8 construct is then transfected into TOP10′F competent E. coli cells, ampicillin resistant cells are selected and plasmid DNA is isolated and checked for construct integrity as described above. This construct is then cotransfected with linearized BacPAK6 DNA into Sf21 insect host cells utilizing the CalPhos™ Mammalian Transfection Kit (Clonetech Inc., Palo Alto, Calif., USA). The insect cells are then incubated for 2-3 days followed by harvest of virus from individual clear plaques. The virus is then amplified in Sf21 cells, the harvested virus titered, and the titered virus used for large scale infection of Sf21 cells utilizing BacPAK Insect Cell Media—all according to the manufacturers recommendations (Clonetech Inc., Palo Alto, Calif., USA). Recombinant HAT-CRF₂R fusion protein is then purified using the TALON® CellThru Purification Kit from Clonetech (Clonetech Inc., Palo Alto, Calif., USA) using conditions recommended by the manufacturer. Briefly, infected Sf21 cells are harvested 48 hours after infection and sonicated in extraction/loading buffer. The cell lysate is then put through a TALONS CellThru column. The column is washed twice with extraction/loading buffer and the bound HAT-hCRF₂R protein is eluted with elution buffer. The eluted protein is analyzed by SDS-PAGE for integrity and protein concentration is quantitated using the Bio-Rad SDS-PAGE system and protein quantitation systems according to the manufacturer's recommendations (Bio-Rad Laboratories, Hercules, Calif.). Purified HAT-hCRF₂R fusion protein is then used for immunizing XenoMouse animals (Abgenix Inc., Fremont, Calif.) for human monoclonal antibody production as follows. 10 μg of purified recombinant HAT-hCRF₂R fusion protein in combination with 25 μg of adjuvant monophosphoryl lipid A (Sigma, St. Louis, Mo.) is used to vaccinate 10 XenoMouse animals multiple times over an eight week period. Serum is obtained from vaccinated animals and utilized in an antigen capture ELISA utilizing purified HAT-hCRF₂R fusion protein to detect antibodies to the HAT-hCRF₂R protein by coating polystyrene ELISA plates (Coming Glass Works, Coming, N.Y.) with HAT-hCRF₂R fusion protein, blocked with PBS-1% BSA, washed and incubated at 37° C. for 1 hour with a 1:50 dilution of the serum samples. After washing 5 times with PBS, the plates are incubated at 37° C. for 1 hour with alkaline phosphatase-conjugated goat antibodies to human immunoglobulin G. The plates are then washed 5×with PBS and antibodies detected with p-nitrophenyl phosphate substrate (Sigma, St. Louis, Mo.) in buffer. Optical densities at 405 nm were measured using a plate reader and signal quantitated. Mice with demonstrated high antibody production are used for hybridoma formation. Hybridomas are generated by fusion of splenic cells from the XenoMouse animals with nonsecreting myeloma cell line NSA-bc12 using a 4:1 ratio of spleen cells to NSA-bc12 cells in the presence of 30% polyethylene glycol PEG1450. Fused cells are individually cloned by limiting dilution into 96 well plates and cultured in RPMI-1640 medium containing 10% fetal bovine serum, nonessential amino acids, sodium pyruvate, L-glutamine, 100 u/ml penicillin-streptomycin and hypoxanthine-aminopterin-thymidine (all from Life Technologies, Rockville, Md.). Supematants from the hypoxanthine-aminopterin-thymidine selected hybridomas were screened for human antibody production by ELISA as described previously. Hybridomas which produce human antibodies to the HAT-hCRF₂R fusion protein are selected for large scale antibody production. Monoclonal antibodies are purified by Protein G-Sepharose chromatography. Briefly, the supernatant from cultured hybridoma clones is loaded onto a Protein G-Sepharose column (SIGMA, St. Louis, Mo.) in loading buffer, washed 3 times and the IgG is eluted with elution buffer. These antibodies are then used for screening to evaluate hCRF₂R activation (agonism) potential. This is accomplished using the methodology as outlined in Example 3. Those human monoclonal antibodies which demonstrate agonist activity toward the hCRF₂R are designated candidate compounds.

Example 9 Determination of Absolute Force Measurement of a Muscle

The extensor digitorum longus (EDL) and soleus muscles are removed, tendon-to-tendon from the casted mouse leg. A silk suture is tied to each tendon of the isolated muscles and the muscles are placed into a plexiglass chamber filled with Ringer solution (137 mM sodium chloride, 24 mM sodium bicarbonate, 11 mM glucose, 5 mM potassium chloride, 1 mM magnesium sulfate, 1 mM sodium phosphate, 0.025 mM tubocurarine, all at pH 7.4 and oxygenated with 95% oxygen/5% carbon dioxide) constantly bubbled with 95% oxygen/5% carbon dioxide maintained at 25° C. Muscles are aligned horizontally between a servomotor lever arm (Model 305B-LR Cambridge Technology Inc., Watertown Mass., USA) and the stainless steel hook of a force transducer (Model BG-50; Kulite Semiconductor Products Inc., Leonia, N.J., USA) and field stimulated by pulses transmitted between two platinum electrodes placed longitudinally on either side of the muscle. Square wave pulses (0.2 ms duration) generated by a personal computer with a Labview board (Model PCI-MIO 16E-4), Labview Inc., Austin, Tex., USA) are amplified (Acurus power amplifier model A25, Dobbs Ferry, N.Y., USA) to increase titanic contraction. Stimulation voltage and muscle length (Lo) are adjusted to obtain maximum isometric twitch force. Maximum titanic force production (Po) is determined from the plateau of the frequency-force relationship.
